Tom Renard — Senior Product Engineer (Frontend)

Bridging the gap between Technical Excellence, Product Strategy, and Business Growth.

I am a Senior Frontend Engineer based in Berlin with over 6 years of experience building high-performance, accessible web applications. Unlike traditional developers, I combine deep technical expertise in React, TypeScript, and Next.js with a Master's in Management. This allows me to not just implement features, but to challenge product requirements, optimize for user adoption, and drive measurable business ROI.

Currently, I am a Senior Engineer at Doodle, where I lead large-scale architectural migrations and performance initiatives. I am obsessed with Core Web Vitals, having recently improved mobile performance scores by 97%.

I am also an advocate for AI-Native Engineering. I leverage tools like Copilot and Cursor to accelerate refactoring, validate architectural decisions, and ship bug-free code faster.

My Core Stack

• Architecture: React 19, Next.js (App Router / RSC), Nx Monorepo

• Performance: Core Web Vitals, Bundle Analysis, Server-Side Rendering

• Quality: TypeScript, Playwright, Vitest, WCAG 2.2 Accessibility
